Hello Lance,
We do offer the DEM-OPA-RGV-EVM , which is an generic EVM board designed for VQFN (RGV) package PLC and DSL line drivers. The associated user's guide showcases the EVM functionality, which can do either two amplifier channels or a single differential…
Hi Gareth,
Allow me to review the schematic and provide feedback by the end of this week, US time.
I see that PI3EQX32904 is a 4-channel redriver, so this will most closely match DS320PR410. However these redrivers are not pin compatible.
We do not have…
Hi Dennis,
We provide some documents for the motor control tuning.

Hi Andreas,
Thanks for the update.
I agree that, operating the device in DEM during start-up and then switching to FPWM should solve this issue. As you already mentioned, DEM is forced during softstart but ends when SS voltage is above 1.2V. I you would…
Hi Adam,
It does look like the DAC is operating fine based on the incorrect reference voltage. You can probe J4 pin 2 while the REF is connected to U2 to know if it's the REF dropping out or U2 that is the issue:
Can you remove the jumper from W1…
Joaquin,
There is an EVM available which you can get from TI.com to test yor circuit (link below)

In your schematic (snippet below) the input swings from 0V to 3.3V, so for the time period in which it is 0V, it…
